I have tried searching the forum for this bug I've enountered a while a go. I always thought it was related to the 'Duplicate order notification e-mail, and duplicate stock decrement' issue which was finally solved in D6-2.7 (http://drupal.org/node/1192018)
But since upgrading this bug kept popping up. It's quite easy to replicate;
- add product to cart and hit checkout
- don't enter any required address fields but just hit review order
- repeat a couple of times
Then go checkout admin/store/orders and you'll see (well in my case) that there is multiple rows of the same order by the same user all in_checkout but with incremented order IDs. So if a user has 10 validation errors in a row the order table is polluted with 10 useless db rows and the order ID is incremented with 10 for no reason.
Has this been mentioned before and can any replicate? Or is it maybe my setup / mix of modules causing this?
